thanks. whats it do??

It increases the fuel pressure which in turn increases throttle response, and maybe top end power....All you do is look at your fuel filter....On the drivers side, their is a copper pipe going into it....The top one is the one your looking for.....Undo it from the fuel filter.....You'll see FPR assembly, and you simply remove the spring, put a BB in, put the spring back, and reassemble everything.

i was told that the sd was different from the obs when doing the bb trick?? blizzard do u know what i need to do.

Yea, just do what i said in the above post...Its really easy, all you need are a couple of wrenches, and some patience. Just find the return line thats plugged into your fuel filter...Its the one on the drivers side, going into the top of the filter....Unscrew the fitting....Its basically screwed onto the pressure regulator...Off the top of my head, I believe there are two allen screws that need to be undone....just be careful undoing them, and once you do, the spring will pop out, just dont lose it....Put the BB in, and reassemble everything.

For the 10k you can use whatever resistor you want technically. The lower number you go the more power and throttle response and smoke, and rougher idle. 18k will make it idle smooooooooooth, 10k it will seem rough-ish. 5.6k (what I have right now) it will idle rough, once it's warmedup it lopes and everybody thinks I'm dumb cause my truck sounds like it's dieing LOL, and 4.4k (ABOBB has this and I want it once I can find where to get the resistor) it will make a steady lope at idle. I know it will be steadier than mine cause it doesn't do it til it warms up. I like the 5.6 because it lopes when idleing along, it smokes enough to be bug people and make me smile, I keep smacking my defuel mark of turbo psi no prob (gotta get a fooler now!). But when you have your foot on the brake and the truck is in gear it doesn't lope it just idles a little high. It's neat.


The only thing I don't like about it is I have the hardest time going 15mph or a slow speed in OD because it is VERY touchy with the 5.6k, and it SHAKES when it idles omg... I can't set a drink on the bedrail while it idles.




You know I always write books lol! Costed me $1.05 btw for the resistor and took literally 2 minutes.

Oh and if I am not too heavy on the pedal i got 2 mpg's better CITY driving!

Yea I use a 5.6k resistor for my "10k mod". My truck idles fine with it actually, I tried swapping in a 1k resistor, and it awesome....Sometimes the truck wont start with that, but when it does, it sounds like a tractor.

Omg! You don't think it starts hurtin stuff at that point? .......How'd it smoke? I'd like to try a 4.4k but radioshack don't have one
Yours isn't lopey huh...?

Ya mean it will smoke with stock tuning? And Im with turboseventhree, is there a point when you start hurting things?

[Jake]

Also, once i get my TW chip, is any kind of effect the restor mod had gone? Like the lopey idle and stuff?
